The commands below are deprecated and should be removed, right?
If you agree, I can carefully work through Chapter 1 to remove/convert all the old unit commands over to the appropriate \SI{}{} command (or \si{} depending on the circumstances).
\newcommand{\M}{\ensuremath{\text{M}}} % Mega
\renewcommand{\k}{\ensuremath{\text{k}}} % kilo
\newcommand{\m}{\ensuremath{\text{m}}} % milli
\renewcommand{\u}{\ensuremath{\mu}} % micro
\newcommand{\n}{\ensuremath{\text{n}}} % nano
\newcommand{\V}{\ensuremath{\text{V}}}
\newcommand{\Ohm}{\ensuremath{\Omega}}
\newcommand{\W}{\ensuremath{\text{W}}}
\newcommand{\A}{\ensuremath{\text{A}}}
\newcommand{\F}{\ensuremath{\text{F}}}
\renewcommand{\H}{\ensuremath{\text{H}}}
\newcommand{\Hz}{\ensuremath{\text{Hz}}}
